Candado MASTER LOCK M178EURD 57 mm de ancho carcasa de zinc Excell combinación autorregulable negro

57mm wide MASTER LOCK padlock with an Excell zinc body and a set-your-own 4-digit combination in black. The lock is designed for enhanced durability and weather resistance while offering simple, tool-free reprogramming of the code. Large ergonomic dials and protective seals help keep internal components working reliably in everyday use.

Advantages

The Tough-Cut octagonal boron-carbide shackle is significantly harder than hardened steel, improving cut resistance. A 57mm wide zinc body includes a reinforced bumper to reduce scratches and wear. The deadlocking mechanism defends against prying, shimming and rap attacks, while a shackle seal and dial dust cover protect internal components and dials. The lock uses a set-your-own 4-digit combination (10,000 possible codes) with no reset tool required, and large ergonomic dials with a blind-dial feature allow operation with gloves or in low light. Limited Lifetime Warranty is provided by the manufacturer.

How to use

Align the dials to open the lock, insert the shackle into the hasp or staple and press closed until it deadlocks.

Recommendations

For best performance, periodically clean the shackle seal and dial area to remove dirt and debris and avoid exposing the lock to corrosive chemicals. Use the lock within its intended applications—such as lockers, gates and storage units—and keep the combination in a secure place to prevent unauthorized access.
